DESCRIPTION
The HCC4093B (extended temperature range) and HCF4093B(intermediate temperature range) are
available in 14-lead dual in-line plastic or ceramic package and plastic micropackage. The HCC/HCF4093Bconsists of four Schmitt-trigger circuits. Each circuit functions as a two-input NAND
gate with Schmitt-trigger action on both inputs. The gate switches at different points for positive and negative-going signals. The difference between the positive voltage (VP) and the negative voltage (VN) is defined as hysteresis voltage (VH) (see fig. 1).
